Among NVIDIA's developer kits, three kits tie for the most GPU CUDA cores at 2,560 each — all built on the Blackwell architecture with 14 CPU cores and 128 GB LPDDR5X:
| Developer Kit | CUDA Cores | GPU Architecture | Memory | Notes |
|---|---|---|---|---|
| IGX Thor Developer Kit | 2,560 | Blackwell | 128 GB LPDDR5X | Includes pre-installed RTX PRO 6000 Blackwell Max-Q dGPU (up to 5,581 FP4 TFLOPS sparse), ConnectX-7 2x 200GbE, BMC |
| IGX Thor Developer Kit Mini | 2,560 | Blackwell | 128 GB LPDDR5X | Compact robotics-safety kit, 2,070 FP4 TFLOPS (sparse) |
| Jetson AGX Thor Developer Kit | 2,560 | Blackwell | 128 GB LPDDR5X | Built on Jetson AGX Thor T5000, 1,035 TOPS, includes Holoscan Sensor Bridge, JetPack 7 |

So there is no single winner — the IGX Thor Developer Kit, IGX Thor Developer Kit Mini, and Jetson AGX Thor Developer Kit share the top spot. If you want a pure Jetson family developer kit (rather than the IGX platform), the Jetson AGX Thor Developer Kit is the leader, followed by the Jetson AGX Orin Developer Kit 64GB with 2,048 CUDA cores. nvidia.comnvidia.com ↗“compute.gpu_cuda_cores=2048”
For reference, the rest of the Jetson developer kit lineup ranks as follows:
| Developer Kit | CUDA Cores |
|---|---|
| Jetson AGX Orin Developer Kit 64GB | 2,048 |
| Jetson Orin Nano Super Developer Kit | 1,024 |
| Jetson AGX Xavier Developer Kit | 512 |
| Jetson Xavier NX Developer Kit | 384 |
| Jetson TX2 Developer Kit | 256 |
| Jetson Nano Developer Kit | 128 |
